The Use of One Sample t-Test in the Real Data
JOURNAL OF ADVANCES IN MATHEMATICS, 2022 The t-statistic is the ratio of the departure of the estimated value of a parameter from its hypothesized value to its standard error. The term "t-statistic" is abbreviated from "hypothesis test statistic".

Robustness of T-test Based on Skewness and Kurtosis
, 2021 Coverage probabilities of the two-sided one-sample t-test are simulated for some symmetric and right-skewed distributions. The symmetric distributions analyzed are Normal, Uniform, Laplace, and student-t with 5, 7, and 10 degrees of freedom.

Case for omitting tied observations in the two-sample t-test and the Wilcoxon-Mann-Whitney Test. [PDF]
PLoS One, 2018 When the distributional assumptions for a t-test are not met, the default position of many analysts is to resort to a rank-based test, such as the Wilcoxon-Mann-Whitney Test to compare the difference in means between two samples.

Multivariate Welch t-test on distances. [PDF]
Bioinformatics, 2016 Motivation: Permutational non-Euclidean analysis of variance, PERMANOVA, is routinely used in exploratory analysis of multivariate datasets to draw conclusions about the significance of patterns visualized through dimension reduction.

Test of T violation in neutral B decays [PDF]
, 2000 T violation should be tested independently of CP violation. Besides K system, B meson decays provide another good place to study T violation. In the Standard Model, T violation in $B^0 \rightleftharpoons \bar{B^0}$ oscillation is expected to be small ...

X-rays from T Tau: A test case for accreting T Tauri stars [PDF]
, 2006 We test models for the generation of X-rays in accreting T Tauri stars (TTS), using X-ray data from the classical TTS T Tau. High-resolution spectroscopy from the Reflection Grating Spectrometers on XMM-Newton is used to infer electron densities, element
